Patent CA-2309704-A1 (CA)
Inventor: TRAUTHEN BRETT
IPC: A61N5/10
Filed: 1998-12-14
Abstract: Disclosed is a dual catheter radiation delivery system, for delivering a dose of radiation to a treatment site, typically in a body lumen. The system comprises an outer sheath catheter, having an inflatable balloon thereon. The system further comprises an inner radiation delivery catheter (30), having a radially expandable structure such as a balloon (48) with a radiation source thereon. The sheath catheter is positioned such that the sheath balloon is at the treatment site, and the radiation delivery catheter is transluminally advanced through the sheath catheter such that the radiation source is positioned within the sheath balloon. The radiation delivery balloon is inflated within the sheath balloon to position the radioactive source near the vessel wall. The source may comprise a thin film carried by the radiation delivery balloon, having a radioactive isotope implanted therein or chemically bonded thereto. Alternatively, the radioactive isotope may be implanted within or adhered to the radiation delivery balloon.

Inventor: MAGNUSSON JAN
IPC: F27B7/34
Filed: 1998-10-13
Abstract: The invention concerns a method for automatized combustion of solid fuel in a combustion apparatus which comprises a burner (1) with a device (1), which is rotatable about the centre axis of the burner for stirring the fuel in the burner which is connected to a boiler (400) and has a feeding-in opening (63, 62) for fuel in the rear end of the burner outside of the boiler and an outlet opening (3) for completely or partly combusted flue gases in the front end of the burner which opens in a combustion chamber (41) inside the boiler which comprises a convection unit (402), from which a hot water conduit (403) extends, said combustion apparatus also including a fan (27) provided to be driven by a second motor (22), here called fan motor, for blowing combustion air into the burner, and a fuel charge feeder (200, 212) for fuel provided to be driven by a third motor (211), here called fuel charge feeding motor. The method is characterised in that the temperature of the water in the hot water conduit is measured, that the measured value is transmitted into a control unit (300), and that the rate of a first motor (34), here called stirring motor, which is provided to rotate said rotatable device for stirring the fuel in the burner, the rate of the fan motor, and the rate of the fuel charge feeding motor are regulated by command from the control unit in dependency of the measured value of the temperature of the water in the hot water conduit which is transmitted to the control unit and in dependency of the heating effect that the burner shall generate according to a control program which is stored in a computer in the control unit, in order that a certain desired temperature of the water in the hot water conduit shall be achieved and be maintained.

Title: Method for on-line analysis of acid catalyst for hydrocarbon conversion process
Inventor: RANDOLPH BRUCE B
IPC: G01N21/35
Filed: 1998-12-16
Abstract: A computer implemented method for on-line determination of concentration in an HF alkylation process catalyst stream containing HF acid, ASO, water and optionally an additive which suppresses the vapor pressure of HF acid. The method employs near-infrared spectroscopy coupled with chemometric data analysis. T'he data analysis uses a partial least squares regression technique which determines unknown concentrations based on spectral calibration data. In use, an absorbance spectrum of material is obtained, e.g. from a slipstream taken from the process alkylation catalyst stream, and the detected spectrum is mathematically analyzed with the aid of the computer to simultaneously predict concentration of HF acid ASO, water and optionally the additive which suppresses the vapor pressure of HF acid.
Patent CA-2317293-A1 (CA)
Title: Apparatus and method for controlling the transmission power of the forward link of a wireless communication system
Inventor: KUO WEN-YI
IPC: H04B7/005
Filed: 2000-08-31
Abstract: A method that adjusts the power level of a set of forward-link signals of a base station responsive to the loading of the forward link as determined by a power level measurement of the signal set. One power level measurement is a pilot fraction of the forward link. Other power level measurements, such as the signal set's power level, can be used, alone or in combination, instead of or in addition to the pilot fraction of the forward link to adjust the power level of the signal set. The power level of the signal set can be changed in any manner, including by scaling it by a scaling factor, or by increasing the power level by a fixed or a variable amount. The power level measurement of the signal set is obtained during a current time period. The scaling factor that will be used in the subsequent time period is determined using the power level measurement. In one embodiment of the invention, the scaling factor can be obtained from a look-up table that is based on the power level measurement. If the cell containing the base station includes several sectors, the power level of the signal set in a sector is adjusted when the power level measurement in that sector indicates that the power level should be adjusted.

Title: An interleaving scheme for blocks in a packet switched system
Inventor: PERSSON MAGNUS
IPC: H03M13/27
Filed: 1999-03-26
Abstract: The present invention discloses a method and system for interleaving blocks of a packet to minimize the effects of burst errors and at the same time enhance the effectiveness of the ARQ protocol. A packet is first divided into a plurality of blocks. Each block is then individually encoded and inner-block interleaved. Thereafter the blocks are interleaved over a longer time period. By performing two stages of interleaving, the present invention allows for the size of a packet block to be kept at a minimum, which increases the effectiveness of the ARQ protocol, and provides greater interleaving of the packet's data elements so as to minimize the effects of burst errors.
